[Conventional technology]
(Conventional LED lamp lighting device and lamp packing)
FIG. 1A is a diagram for explaining a conventional LED lamp lighting device 100, and FIG. 1B is a diagram for explaining a lamp packing 800 used therein, the left side being a perspective view and the right side being a sectional view. be. The LED lamp illumination device 100 includes an LED lamp 200 having a base 600 formed at one end, and a socket 400 to which this lamp is attached. An LED unit (not shown) is housed inside a translucent cover 200 a of the LED lamp 200 . The translucent cover 200a is supported by a housing 200b, and a base 600 is formed around a connecting member 200c integrated with the housing. The base 600 is screwed into the receiver 500 arranged in the recess of the socket 400, and power is supplied to the LED unit through the base.

A cylindrical lamp packing 800 is arranged in the gap between the base 600 of the LED lamp 200 and the socket 400 . This lamp packing 800 is for anti-vibration, and it is assumed that it will be used in a sealed housing. Therefore, although the lower end of the packing enters the gap between the base and the socket to prevent direct contact, water enters. There may be a gap of some degree, and the waterproof function is not taken into consideration.

(Another conventional LED lamp lighting device and lamp packing)
FIG. 2A is a diagram for explaining another conventional LED lamp lighting device 200, and FIG. 2B is a diagram for explaining a lamp packing 810 used therein. It is a diagram. The LED lamp illumination device 200 includes an LED lamp 210 having a base 610 formed at one end, and a socket 410 for mounting this lamp.

A cylindrical lamp packing 810 as shown in FIG. 2B is arranged in the gap between the base 610 of the LED lamp 210 and the socket 410 . Since the neck portion of the LED lamp 210 is shaped to fit the groove formed on the inner surface of the upper end portion of the lamp packing 810, the LED lamp 210 and the lamp packing 810 are tightly fixed. Further, since the cylindrical lamp packing 810 is of a type in which the upper end portion of the socket 410 is press-fitted into the groove 810a formed inside, it has excellent adhesion to the socket. However, this press-fitting work process becomes a bottleneck, and it is difficult to improve productivity when mass-producing the LED lamp lighting device 200 . In addition, since the shape of the neck portion of the LED lamp 210 is complicated, it is necessary to add a neck portion of a resin molded product in order to apply it to the glass outer bulb, which increases the manufacturing cost.

(Another conventional LED lamp lighting device and lamp packing)
FIG. 3A is FIG. 3 of Patent Document 3 (Utility Model Registration No. 3156168), and FIG. 3B is a diagram explaining the lamp packing used in the LED lamp lighting device shown in FIG. 3A.

In Patent Document 3, an LED lamp 3 ( luminaires) are disclosed. With the packing 1 disclosed in Patent Document 3, when the lamp 3 is screwed into the socket 23, the upper and lower surfaces of the packing 1 must be pressed between the socket 23 and the base end portion 11 of the lamp 3 to be in close contact. That is, in the LED lamp 3 of Patent Document 3, it is necessary to provide a base portion that is long by the thickness of the packing 1 for a socket with a specific depth.

In Patent Document 3, a collar 15 is provided separately from the fitting of the mouthpiece in order to extend the mouthpiece. Paragraph 0027 of Patent Document 3 states that a gap may be provided between the packing 1 and the collar 15, but in this case, the packing 1 may fall when the lamp 3 is attached to the socket 23. be. In order to prevent the dropping, it is necessary to stipulate that the inner diameter of the packing 1 is smaller than the outer diameter of the collar, as defined in claim 3 of Patent Document 3. Moreover, since the packing 23 of Patent Document 3 does not cover the shell 17 of the mouthpiece 9, it does not have an electric shock prevention function.

[This embodiment]
(LED lamp illumination device)
FIG. 4A is a diagram illustrating an LED lamp illumination device according to this embodiment. The LED lamp illumination device 10 consists of an LED lamp 2 and a socket 4 to which it is mounted. The LED lamp 2 has a glass outer bulb 2a containing an LED element (not shown) and a screw base 6 (cylindrical electrode formed with a male screw; also called an "E-type base"). is doing.

The socket 4 is formed with a concave portion 4a having a predetermined depth from the upper surface, and a receiving metal (cylindrical electrode having a cylindrical female screw; not shown) is arranged. A base 6 of the LED lamp 2 is screwed into a base of the socket 4 to fix the lamp and to supply power to the lamp. The socket 4 is provided with mounting metal fittings 4c according to the installation location of the LED lamp illumination device. Symbol CL denotes the lamp axis. A lamp packing 8 is provided so as to surround the joint between the LED lamp 2 and the socket 4 .

A packing 14 is also arranged in the gap between the lamp outer bulb 2a and the upper portion of the socket 4 (this portion is also called a "lamp holder"). However, the feature of this embodiment resides in the lamp packing 8, and the explanation of the packing 14 is omitted because it is not directly related.

FIG. 4B is a partially enlarged view for explaining the details of the lamp packing 8 used in the LED lamp lighting device shown in FIG. 4A. Although it is hidden by the lamp packing 8 in FIG. 4B, as can be seen in the drawing on the right side of FIG. in direct contact. That is, the present invention can also be applied to a lamp that does not have a collar for holding a packing like the lamp of Patent Document 3.

The lamp packing 8 generally has a cylindrical shape that tightly surrounds the base 6 . The lamp packing 8 is made of any elastic material having insulation, heat resistance, waterproofness, elasticity and good thermal conductivity. Typically, the lamp packing 8 is made of polyurethane rubber, silicon rubber, or the like.

The lower end portion 8b of the lamp packing 8 abuts against the upper end surface 4b of the socket 4 and is pressed upward along the lamp axis as indicated by the arrow. The upper end portion 8a of the lamp packing 8 abuts on the neck slope portion 2b of the LED lamp 2, and elastically deforms so that the diameter expands along the neck slope portion 2b at the portion indicated by the broken line frame 8c. Upward movement along the axis is blocked.

In other words, the lamp packing 8 is positioned and held between the inclined neck portion 2b of the LED lamp 2a and the upper end surface 4b of the socket 4 in a compressed state where a predetermined external force is applied in the lamp axial direction. The lamp packing 8 continuously covers from the neck part of the LED lamp 2 to the upper part of the shell (screw part) of the base 6, and even if the upper part of the base 6 protrudes from the socket 4, a person carelessly touches it and gets an electric shock. there is nothing

Especially in a lamp with a glass outer bulb, distortion is likely to occur when a screw shape is formed in the neck portion. Therefore, it is difficult to form a component having a complicated shape in the vicinity of the neck portion like a resin-molded lamp. By using the packing of the present invention, it is possible to easily obtain a sealed structure between the socket and the outer bulb by fitting the packing to the neck portion of the outer bulb having a normal shape (similar to that of an incandescent lamp).

(Procedure for attaching the lamp packing)
5A and 5B are diagrams for explaining a step of mounting the lamp packing in manufacturing the LED lamp lighting device according to the present embodiment. The left side of the drawing is a flowchart of the mounting process, and the right side is an explanatory diagram of the lamp packing mounting process in each process. Note that the lower half of each lamp outer sphere is hatched, which indicates the region of the reflective film formed on the inner surface of the outer sphere. LED lamps include both lamps with a reflective film and lamps without a reflective film.

In step S1, the lamp packing 8 is inserted into the lamp base 6. As shown in FIG.
In step S<b>2 , the lamp packing 8 is mounted on the socket 4 , and the lower end surface 8 b of the lamp packing 8 is brought into contact with the upper end surface 4 b of the socket 4 .
In step S3, the lamp packing 8 is slid upward by pushing the lamp 2 into the socket 4 and screwing the base 6. As shown in FIG.
In step S4, the upper portion 8a of the lamp packing 8 slides on the surface of the neck slope portion 2b of the lamp 2 and elastically deforms to engage (the portion indicated by the dashed frame 8c in FIG. 4B), and the lamp packing 8 stops at the proper position. do. In this manner, the lamp packing 8 is automatically positioned at the appropriate position without using a special positioning device, and is engaged with the lamp neck inclined portion 2b with a high adhesive force by pressing the socket 4 upward. retained.

Alternatively, the LED lamp device can be completed by shipping the LED lamp with the packing in the state of step S1 and attaching it to an existing incandescent lamp socket at the site.

(Lamp packing specifications)
FIG. 6 is a partially enlarged view illustrating a state in which the LED lamp 2 of the LED lamp lighting device 10 according to this embodiment is attached to the socket 4. As shown in FIG. The inventors have determined preferable dimensional specifications for the size of the lamp packing 8 through trial production of the LED lamp lighting device.

For the inner diameter RPi of the lamp packing, the upper limit was set so that the lamp packing would not drop even if the base was turned downward, and the lower limit was set so that the workability of fitting the lamp packing to the base was not lost. As a result, the inner diameter RPi of the lamp packing was set within the range of −10% of the outer diameter of the base≦inner diameter RPi≦+10% of the outer diameter of the base.

When the lamp packing is made of polyurethane rubber or silicone rubber, the thickness RPt of the lamp packing is set to the upper limit of the common-sense maximum size, and the lower limit of the minimum thickness to secure the repulsive force during press deformation. did. As a result, the thickness RPt of the lamp packing was set within the range of 1.5 mm≦thickness RPt≦15 mm.

The lamp packing length RPL varies depending on the base type. Here, as shown in FIG. 6, the dimension [mm] of each part in the direction of the lamp axis is referred to as follows.
NSL: Length of neck slope
RPL: Length of lamp packing
PAE: Length of lamp packing covering the slope
CAL: Base length
CAE: Extension (Long jaw type)
CAS: Standard Base Length A “long base type” is a type of LED lamp with a base that, when installed in an existing incandescent light bulb socket, hides the lighting circuit of the LED lamp inside the base so that it looks the same as an incandescent light bulb. In order to make it possible, it is a type of mouthpiece with an extended mouthpiece length compared to the standard mouthpiece length. Also, when the LED lamp is attached to the socket 4, the upper end of the socket 4 is at the same position as the upper end of the standard base length. Since the upper end of the lamp packing 8 is positioned against the sloped neck of the lamp, the length RPL of the lamp packing is defined as the extension CAE + the length PAE of the lamp packing covering the sloped portion (RPL = CAE + PAE).

The length PAE for which the lamp packing covers the inclined portion is sufficient at a minimum greater than zero and a maximum of about 15 mm (0<PAE≦15 mm).

(1) For E26 type caps, the standard cap length CAS is 25 mm. Therefore, the extension CAE is the base length CAL-25 mm (CAE=CAL-25 mm). The E26 type cap with a cap length of 25 mm is correctly described as E26/25, which means the diameter of the cap and the length of the cap. However, in many cases, the base length is omitted and displayed as E26. E26 caps with a cap length other than 25mm also exist, but in that case, always specify the cap length after a slash like E26/27. In addition, the E27 type E cap is also used mainly for overseas lamps, but the outer diameter is almost the same as the E26 series, so if the cap length is the same, the same packing can be used.
In RPL=CAE+PAE, CAE=CAL-25 mm and 0<PAE≦15 mm, so the length RPL of the lamp packing is CAL-25 mm<RPL≦CAL-25 mm+15 mm, that is, CAL-25 mm< It is within the range of RPL≤CAL-10mm.

(2) For E39 type caps, the standard cap length CAS is 41 mm. Therefore, the extension CAE is the base length CAL-41 mm (CAE=CAL-41 mm). As with the E26 type, the E39 type also has a base with a base length other than 41mm, in which case the base length must be specified after the slash. Also, the E40 type E base is mainly used for overseas lamps, but the outer diameter is almost the same as the E39 series, so if the base length is the same, the same packing can be used.
In RPL=CAE+PAE, CAE=CAL-41 mm and 0<PAE≦15 mm, so the lamp packing length RPL is CAL-41 mm<RPL≦CAL-41 mm+15 mm, that is, CAL-41 mm <RPL≤CAL-26mm.

The extension PAE of the length of the lamp packing covering the inclined portion is preferably determined according to the shape of the inclined portion of the lamp to which the lamp packing is applied, regardless of the size of the base. That is, when the angle of inclination of the inclined portion with respect to the lamp axis CL at the point where the lamp inclined portion contacts the shell 17 of the base 6 is close to 90 degrees, the PAE is preferably close to the minimum value (greater than 0 mm). On the other hand, when the tilt angle is as small as about 15 degrees, it is preferable to select a value close to the maximum value for PAE.

The length RPL of the lamp packing is preferably twice or more the thickness RPt of the lamp packing. In an LED lamp with a lamp packing, it is preferable that the lamp packing be easily inserted into the base and not fall off. This is because the length in the CL direction must be at least twice the thickness RPt of the lamp packing. When tapered portions are provided at the top and bottom ends of the lamp packing, the thickness RPt of the lamp packing can be made thinner than the above-mentioned "1.5 mm" at the ends, but preferably at least 0.8 mm. This is because the packing as an insulator must have a thickness of 0.8 mm or more in order to ensure sufficient safety for electric shock protection. In this embodiment, when the LED lamp 2a is attached to the socket 4, the inclined neck portion 2b of the lamp is accommodated in the concave portion 4a of the socket. 0.8 mm is required for

The hardness RPh of the lamp packing was set within the range of 40 to 60 in terms of Shore hardness. A type A durometer (JIS K 6253 compliant) is used for this hardness measurement. In the example, the hardness was RPh=50 (Shore A50).

(Shape of lamp packing)
FIG. 7 is a diagram illustrating the shape of the lamp packing 8 of the LED lamp lighting device 10 according to this embodiment. (A) is a typical example, and (B) and (C) are modifications. In each example, the left is a perspective view and the right is a sectional view.

(A) is a typical example, and the lamp packing 8-1 has a cylindrical shape. The upper end face 8a is flat (in other words, perpendicular to the axis) and has an annular shape. The same applies to the lower end face (not shown).

In the modified example shown in (B), the upper end surface 8a of the lamp packing 8-2 that abuts on the neck slope portion 2b of the lamp 2 is shaped to fit the slope portion 2b. Specifically, the annular upper end face 8a is an inclined end face with the inner circumference lower than the outer circumference. As a result, the area of contact between the inclined neck portion 2b of the lamp and the upper end face 8a of the lamp packing is further enlarged, and the adhesion is improved.
Although not shown in the drawings, the lower end face 8b of the lamp packing that abuts against the upper end face 4b of the socket 4 may be shaped to fit the upper end face 4b. In the example shown in FIG. 4B, the annular upper end face 4b of the socket 4 is an inclined end face with the inner circumference lower than the outer circumference. To conform to this, the annular lower end face 8b of the lamp packing may be an inclined end face with the inner periphery lower than the outer periphery. As a result, the contact area between the upper end face 4b of the socket 4 and the lower end face 8b of the lamp packing is further enlarged, and the adhesion is improved.

In the modified example shown in (C), the upper portion of the lamp packing 8-3 that abuts on the neck slope portion 2b of the lamp 2 is partially thickened. By partially increasing the thickness RPt of the lamp packing, the strength of adhesion between the lamp and the inclined neck portion 2b of the lamp is further increased, and the adhesion is improved.
Although not shown in the drawings, the lower portion of the lamp packing that contacts the upper end face 4b of the socket 4 may be partially thickened.

Furthermore, as shown in (C), the partially thickened upper and lower end surfaces may be inclined as shown in (B) so as to fit the shape of the contact member.

(shape of lamp outer bulb)
This embodiment is mainly characterized by the shape of the lamp packing. Therefore, as long as it is an LED lamp with a base, the lamp outer bulb may have any shape. For example, although not shown in the drawing, the lamp outer bulb may be of any shape such as a BT shape, tube shape (T shape), ball shape, bulb shape (eggplant shape), and the like.

[Advantages and effects of this embodiment]
(1) In most LED lamps with a base, the diameter of the LED lamp is larger than the diameter of the base, so the lamp outer bulb (in the case of Fig. 6) or the connecting member (in the case of Figs. 1A and 2A) must inevitably have There is an inclined plane. When the lamp packing is pushed upward, its upper portion expands due to elastic deformation, and is engaged and held in a state of overlapping with these inclined surfaces.

(2) According to the LED lamp lighting device according to the present embodiment described above, by adopting a novel lamp packing, the lamp packing is automatically positioned at an appropriate position during manufacturing of the lighting device, and the socket and the inclined portion of the lamp while being pressed in the axial direction of the lamp. Therefore, one end of the lamp packing is tightly attached to the socket, and the other end is firmly attached to the lamp. An LED lamp lighting device with such a novel lamp packing is a novel lighting device compared to the prior art, and cannot be easily conceived based on the prior art.

An example of the embodiment of the LED lamp illumination device according to the present invention has been described above, but the present invention is not limited to this. Additions, deletions, modifications and improvements to these embodiments are within the scope of the invention. The technical scope of the present invention is defined by the description of the appended claims.
